Photosmart 8750 carriage jammed error and skewed printing

In Publisher only, the printer skews the document until I get a carriage jammed error. It says to turn off printer to fix the problem. Paper feeds through fine, other documents print fine; I have reinstalled Publisher and printer driver and still get problem.

I have the same problem but with Phoroshop CS2 and only intemittently and only with photo-quality printing. The steps ourlined do work but the problem comes back after 6-10 sheets or so.

The
Carriage Jam
error message displays on the control panel display. The print
carriage, which holds the ink cartridges, stalls against the left side
of the printer. A paper jam might have occurred previously.

If you have had paper jam and not replaced the rear paper grey plastic retainer correctly or somehow it has become loosened the paper will twist on entry and the printing will be askew. Sometimes not loading paper. It will then also not align when replacing cartridge. Had this problem, took out the retainer that has two plastic points that should locate in the retaining holes and pushed it back. Paper jam, printouts and alignment was then fine. Took me months to figure out as it was printing, just not very straight

First you need to determine if it is optical skew or mechanical skew.
If the machine is used as a printer then do the computer prints come out skewed? If it is not connected to a PC then print out the counter list using UserTools/Counter. If that prints straight then you are dealing with optical skew. Ricoh's in general are bad about the left front corner of the machine drooping from someone pushing down on that corner. If you have optical skew try lifting up the left front corner of the copier and try making a copy. That might fix your problem.
If the UserTools/Couter print out is skewed then your back to a mechanical skew and there are numerous causes for that.
The optical skew is more likely so let's start there.

Lift the printer cover. undo the 2 screws (torx head). remove the right hand end of the printer casing.

You will see a blavck plastic moulding with a couple of gears (it controls the cartridge cleaning). This is the cause of your jam - it is out of sync. Turn the machine on and watch what happens with this moulding you will see what I mean by out of sync and it can just be gently pushed back into alignment. Once it is ok turn the unit off and then on again and your jam should be cleared. Put it back together again and print away.

Sounds like when you pulled out the paper jam, you misaligned the print carriage. That would produce both the noises you hear and the print quality issues. HP.com has a few web pages on their site that might help. The first one deals with noisy print carriages. Unfortunately, it's not dedicated to just your product, but the steps should generally apply:

If all else fails, unplug the power cord from the printer, wait 20 seconds or so, then plug it back in. That should restart the printer and make it go into a self test which may include a realignment procedure. Watch for any error messages on the display on the printer's control panel. Sometimes to realign, it prints out two test pages and instructs you to place the first printout on the scanner bed and then press Enter.

Go to the following web page and when it opens, scroll down to the section "Replacing the print cartridges", and find step 9 in that section for alignment instructions.
